There are three primary components of fertiliser, and you may see them on products as three numbers representing the percentages of nitrogen, phosphorus, and potassium.

How to feed grass tips mentioned in this video:

• A good idea is to fertilise twice a year. Give your grass a boost in spring and again in autumn, and you will have a strong summer lawn and grass that is prepared for winter.
• Fertiliser comes in different forms. A good idea is to feed your grass steadily over the summer by treating it in spring with a slow-release fertiliser. These granules will release food over many weeks and keep the grass fed at a time when it is growing fast. In summer we use our lawns more and the weather may be hot and dry, grass can get stressed and needs nutrients to keep it strong and green.
• In the autumn, after a hard-working summer, your grass will appreciate a boost before the cold winter months come. This feed is different from the spring one; don’t be tempted to fertilise with the same feed as spring, as it is high in nitrogen for new growth. As temperatures fall, grass growth slows so all you are doing is strengthening the plant as it winds down for winter.
• Apply the correct amount of fertiliser– you can damage or burn grass if you use too much. Remember to wash off the fertiliser by watering your lawn as leaving fertiliser on the blades of your grass can cause damage. Rates are per square metre, so make sure you have enough to cover your area. You can apply granules by hand or by spreader. For liquids, use a watering can or sprayer, depending on the size of the area you need to cover.
